Robert "Bob" Nesta Marley OM (February 6, 1945 – May 11, 1981) was a Jamaican singer, songwriter, guitarist, and activist. He is the most widely known performer of reggae music.

Marley is best known for his reggae songs, which include the hits "I Shot the Sheriff", "No Woman, No Cry", "Three Little Birds", "Exodus", "Could You Be Loved", "Stir It Up", "Jamming", "Redemption Song", and "One Love". His posthumous compilation album Legend (1984) is the best-selling reggae album ever, with sales of more than 12 million copies.

Marley was born in the small village of Nine Mile in Saint Ann Parish, Jamaica as Nesta Robert Marley. A Jamaican passport official would later swap his first and middle names. His father, Norval Sinclair Marley, (born in 1895), was a white Jamaican of English descent, who lived in Liverpool. Norval was a Marine officer and captain, as well as a plantation overseer, when he married Cedella Booker, a black Jamaican then eighteen years old. Norval provided financial support for his wife and child, but seldom saw them, as he was often away on trips. In 1955, when Marley was 10 years old, his father died of a heart attack at age 60. Marley suffered racial prejudice as a youth, because of his mixed racial origins, and faced questions about his own racial identity throughout his life. He once reflected:

I don't have prejudice against himself. My father was a white and my mother was black. Them call me half-caste or whatever. Me don't dip on nobody's side. Me don't dip on the black man's side nor the white man's side. Me dip on God's side, the one who create me and cause me to come from black and white.

Marley and his mother moved to Kingston's Trenchtown slum after Norval's death. He was forced to learn self-defense, as he became the target of bullying because of his racial makeup and small stature (5'4" or 163 cm tall). He gained a reputation for his physical strength, which earned him the nickname "Tuff Gong".

Marley became friends with Neville "Bunny" Livingston (later known as Bunny Wailer), with whom he started to play music. He left school at the age of 14 and started as an apprentice at a local welder's shop. In his free time, he and Livingston made music with Joe Higgs, a local singer and devout Rastafari who is regarded by many as Marley's mentor. It was at a jam session with Higgs and Livingston that Marley met Peter McIntosh (later known as Peter Tosh), who had similar musical ambitions.

In 1962, Marley recorded his first two singles, "Judge Not" and "One Cup of Coffee", with local music producer Leslie Kong. These songs, released on the Beverley's label under the pseudonym of Bobby Martell, attracted little attention. The songs were later re-released on the box set, Songs of Freedom, a posthumous collection of Marley's work.
